Application filed May 7, 1910. Serial No. 559,936.

' To all whom it may concern:

Be it known that I, SOLOMON KARPEN a citizen ofthe United States,residing at.Chi-- cago, in the county of Cook and State of Illinois,have invented a new and useful Improvement in Sofa-Beds, of which thefollowing is a specification.

My invention relates particularly to combmation sofas and beds, orcombination couches and beds, in which a foldable mattress-frame, orfoldable bed-frame, is nor- 'mally housed within themain-frame beneaththe seat'of the sofa and equippedwith a foldable wire-mattress, orspring bed-bottom, the parts being so related as toafford room betweenthe sections of the folded bedframe and bottom for the bedding, 2'. e.,the mattress-pad, bed-linen and covers.

The present invention constitutes an improvement upon theconstructionset forth in my LettersPatent No. 949,374, granted February 15, 1910;and my primary object is to providea structure of improved constructionand operation whereby the forward shifting of the folded bed whichoccurs in this type of structuremay be accom plished through the mediumof, Links and levers and whereby the bed will-at thesame time beelevated so that when unfolded it) will "occupy a position approximatin'in height the height of "an ordinary bed o the.

standard or non-folding type.

It may be'preliminarily stated that inthe preferred construction of theinvention -which is illustrated in the accompanying drawings, there areemployed a main framea stationary back carried thereby; a seat mountedbetween theend standards of the main frame and adapted to swingrearwardly and upwardly and assume-a stand-v ing position adjacent the.sofa-back; a foldable mattress-frame normally housed within the mainframe beneath the seat; and link and lever devices adapted to carrythefolded bed from its housed position to the position for unfolding,and vice versa. The Construction is preferably such that the'jfolded bedwill be automatically shifted forwardly and elevated in the operation ofswinging the seatfrom the horizontal 'to the. standing position, andwill be automaticallyreturned' to the housedposition in the operation oflowering the seatfrom the standing osition to the horizontal position.As has een indicated, the -mattress-frame.-'is preferably e'quippedwi'thaflexible mattress, or be ferried manner;

bottom, which is unfolded or spread in the operative position intheoperation of unfolding the' bed-frame; and the mattresspad, ormattress proper, and other bedding, includingthefbed-linen and covers,are secured in position and folded between the sections of the foldablemattress-frame, so that thebedd-ing will be spread out with the mattressor flexible bed-bottom when the device is converted to bed-form.

In the accompanying drawings, which show my improved sofa-bed in itspreferred form-Figure 1 represents a sectional view of my improvedcombined sofa and bed, illustrating the device in sofa-form, with thefolded bed housed in the main frame beneath the sofa-seat; Fig. 2, abroken sectional view taken, as indicated, at line 2 of Fig. 3, andshowings. truss employed in connection'. with the intermediatebed-section; Fig. 3, a section similar to Fig. 1 but showing the deviceafter conversion'to bed-form; and Fig. 4, a broken plan sectionalwiewshowing the structure in the bed-forming position.

In he preferred construction, .A represents the main frame; B, asofa-back fixedly secured between the end-standardsthereof; O, aswinging sofa-seatadapted to swing rearwardly and upwardly fromitshorizontal position and assume a standing position adjacent saidback; D, a foldable bed-frame -.o1- mattress-frame normally housed infolded condition within the main frame beneath the sofa-seat; andE linkand lever mechanism adapted to carry the bed from the housed position tothe position for unfolding, and

" vicev versa.

The frame A may be of any suitable construction, In the constructionillustrated, the frame comprises wooden end-standards 1 which constitutethe arms of the sofa; a rear connecting bar 2joining the rear lowerportions of said end-standards; a front connecting member 3 joiningthelower front portions of said end-standards and constituting a frontpiece for the main frame; and endpieces 4 connecting the end-portions ofthe members 2 and 3 and forming therewith a box, said members 'lyingadjacent the inner surfaces of the lower portions of said endstandards,As will be understood, the endstandardsmay be made as plain or asornamental as desired. i

Theback' B maXsbe attached in-any preshown, it its between frame, Dpreferably comprises a rear fra me section 8 of U-form; an intermediateframesection 9having the rear ends of its members pivotally connectedwith the front ends of the arms of the section 8;;a front framesection10 of U-form and having the extremities of its arms pivotally connectedwith the front ends ofthe end-members oithe frame-section 9; and a truss11 having its upturned arms pivotally connected with the intermediateportions of the end-members of the section 9. The "frame-section 8comprises a rear longitudinal member 12 i and end-members 13 whichconstitute the forwardly-turned arms of the U-shaped members. ThesectionQ is composed of bars whose rear ends are connected by pivots 14with the front ends of the arms 13 of the rear section 8.v Thefront-fra'me section comprises a longitudinal member 15 and end-members16- constituting the rearwardl'y-i .turned arms of the U-shapedframe-section. The extremities of the arms 16 are joined by pivots 17to.the-,front ends of the bars composing the section 9. The arms 13 and16 and the bars com osing the section 9 are of angle-form and t e barsof the section 9 are adapted to overlap with the end-portions of thearms 13 and 16, so that while the bedsections may be unfolded so astolie in the same plane, the joints are such as to prevent the sectionsfrom turning too far, or, in other words, beyond the plane which thesections normally occupy in the extended pcsition. The truss 11, in theform shown, comprises (Fig. 2) a longitudinal channelbar 18 equipped atits extremities with upturned arms 19 and braces 20 for said arms. Theupper ends of the arms 19 are notched, as indicated at 21, toaccommodate the bars composing the intermediate bed-section 9, and saidbars are connected with said arms 19 by pivot-bolts 22. A foldablewire-mattress, or spring bed-bottom, 23 is stretched between the'foldably-connected end-members of the bed-frame,-as indicated in Fig.4.

The link and lever mechanism E, in the 24 (one at each end of thesofa-bed), mountthe front. ends of said levers 24 carrying the pivots 22which support the intermediate form illustrated, comprises a pair ofleversbed-section 9; a pair of links'27, connected at one end by pivots28 with the levers 24 and near the other end by pivots 29, with slides30 mounted on the arms 13 of the rear bed-section; a pair of arms 31rigidly secured at their upper ends to the'rear portions of theend-members of the seat-frame 6 and connected by pivots 32 with the rearends of the levers 24; and links 33 and 34, whose upper ends areconnected, respectively, by pivots 35 and 36 with the attachi'ng.or baseportions of the arms 31, and whose lower ends are connected,respecitvely, bypivots 37 and 38 with bars or members 39, which arerigidly secured to the frame members 4, being separated from saidframe-members by spacing-blocks 40. The upper ends of the links '25are'joined with the intermediate portions of the levers 24 by pivots 41.The links 27 have extensions above the pivots 29 which are joined by"links 42 to the end-members .16 of the front bed-section 10 near thepivotal connections 17. The'bed-section 10 has connected therewith, nearthe free or swingin edge thereof, legs 43 which are joined by links 44to the bars constituting the intermediate bed-sec tion 9. The truss 19dependsfrom the intermediate bed-section, and the longitudinal member 18of said trussis disposed at a suitable distance beneath the springbedbottom.

The rear portions of the levers 24 have horizontal position to thestandingposition.

Assuming the bed to have been properly made up, that is, the bedding tohave been properly spread and secured to the foldable bed-frame, beforethe conversion of the structure to sofa-form,,the structure may beconverted to bed-forin/by raising the seat C to the standing positionand then unfolding the bed.- In the operation of raisingthe seat to thestanding position, the arms 31 attached to the base-portion of the seatare turned forwardly from the position shown in Fig. 1 to the positionshown in Fig. 3, in'which operation the folded bed, mounted on thelevers 24. is bodily shifted forwardly and elevated. The' springs 45assist in this cperation, and the links 33 and 34' swing forwardlysomewhat from the position shown in Fig.1 until they assume the pos tionshown in Fig. 3. After the folded bed has been bodily shiftedautomatically in the opweight of the parts assists in applying tenter asto dispose the bed, when the structure stood therefrom, but the appendedclaims the operation the legs 43 will be extended forwardlyand'elevating it, when it is again prising a tions, and

the operation of raising and lowering the seat.

eration of raising the seat, the bed may be unfolded by the operatorgrasping the rear or free edge: of the front or su erposed sect-ion andswinging the same orwardly, inwhich operationthe intermediatebed-section will turn on the pivots 22 carried by the support-ing levers'24, and the links '42 will operate 'to draw the" slides 30 j forwardly,therebyswin 'ng the rear end of the lower most or rear'Io ed-sectionupwardly. During through the medium of the links 44, and at the end ofthe operation, the bed will be un-' folded and occupy theposition' shownin Fig. 3. Inthe reverse operation the bedding is first properly spreadand secured to the mattress-frame in the usual manner, after which-thefront bed-section 10 is swung upwardly andrearwardly, which results inturning the intermediate section on the piv-- ots 22, and at the sametime the slides 30 are moved rearwardly, thereby swingingthe rear end ofthe rear bed-section 8 down-, wa-rdly. The folded bed is thenautomatically retracted and lowered in theoperation of swinging the seatdownwardly from the standing position. In this operation, the

sion to the springs 45,t'hereby stor1ng power to aid in the operation ofshifting the bed desired to convert the structure to bed-form.

The structure described is of'such characis converted to bed-form, at aconvenient height, corresponding with the height of the standard bed ofthe non-folding type.

The foregoing detailed description has been given for clearness ofunderstanding only, and no undue limitation is to be underare to becdnstrued as broadly as permissible in view of the prior art. I
